Pasi pemumwe mutoro, nhamba yemarevolutions kana maawa ayo akuberekazviitiko kusati kwaitika pitting inonzikuberekahupenyu.
Hupenyu hwekutenderera kunotsanangurwa nehuwandu hwekuchinja (kana maawa ekushanda pane imwe spidhi): mukati mehupenyu huno, kutakura kunofanirwa kuve nekutanga kuneta kukuvadzwa (spalling kana chipping) pane chero zvindori zvekutakura kana zvinhu zvinotenderedza. Nekudaro, kungave murabhoritari bvunzo kana mukushandisa chaiko, zvinogona kunyatsoonekwa kuti hupenyu chaihwo hwekuberekasnechitarisiko chakafanana pasi pemamiriro akafanana ekushanda akasiyana zvakanyanya. Uye zvakare, kune akati wandei dudziro dzakasiyana dzekubereka "hupenyu", imwe yacho inonzi "hupenyu hwekushanda", iyo inoratidza hupenyu chaihwo hunogona kuwanikwa nekutakura kusati kwaitika nekuda kwekupfeka, kukuvara hakuwanzo kukonzereswa. kuneta, asi Inokonzerwa nekupfeka, ngura, kukuvara kwechisimbiso, nezvimwe.
Kuti uone chiyero chekubereka hupenyu, hupenyu hwekutakura uye kuvimbika kune hukama.
Kuti uenzanise kutakura kugona kweiyo bearing against pitting corrosion, kana yakayerwa hupenyu hwekuberekainotsanangurwa kuve miriyoni imwe shanduko (106), iyo yakanyanya kuremerwa inogona kutsigirwa ndiyo yakakosha yakatemerwa simba remutoro, inomiririrwa naC.
Kureva kuti, pasi pechiito cheiyo rated dynamic load C, kuvimbika kwerudzi urwu rwekuberekakushandira miriyoni imwe chete marevolutions (106) pasina pitting kukundikana i90%. Iyo yakakura C, iyo yakakwirira yekutakura simba.
Yekutanga dynamic load rating
1. Radial bearing inoreva pure radial load
2. Thrust ball bearings zvinoreva pure axial mitoro

Kuti uone chiyero chekubereka hupenyu, hupenyu hwekutakura uye kuvimbika kune hukama.
Nekuda kwekusiyana kwekugadzira kwakaringana uye kufananidzwa kwezvinhu, kunyangwe batch imwechete yemabhengi echinhu chimwe uye saizi, inoshandiswa pasi pemamiriro ekushanda akafanana, ane hupenyu hwakasiyana. Kana hupenyu hwehuwandu huri 1 unit, hupenyu hurefu hwehukama huri 4 units, hupfupi ndeye 0.1-0.2 unit, uye chiyero chehurefu kune hupenyu hupfupi 20-40 nguva. 90% yemabhengi haaburitse gomba, uye huwandu hwemarenduru kana maawa anowanikwa anodaidzwa kunzi bearing rating hupenyu.
Kuti uenzanise kutakura kugona kweiyo bearing against pitting corrosion, kana yakayerwa hupenyu hwekuberekainotsanangurwa kuve miriyoni imwe shanduko (106), iyo yakanyanya kuremerwa inogona kutsigirwa ndiyo yakakosha yakatemerwa simba remutoro, inomiririrwa naC.
